To all whom it may concern."

Be it known that I, CARL v. LDE, engineer, a subject of the King of Prussia and German Emperor, residing at Arbon, Switzerland, have invented certain new and useful Improvementsjn Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Patents have been obtained for thisinvention as follows: Germany, No. 48,487, June 14, 1889; Austria-I-Iungary, No. 9,123 and No. 29,851, June 28, 1889; Switzerland, No. 639, October 3, 1889; France, No. 196,307, Aprill?, 1889; England, No. 11,502, July 30, 1889; Belgium, No. 88,229, November 15, 1889, and Italy, No. 26,345/68, November 25, 1889. p

This invention relates to pumps; and it con- Sists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a vertical section through a pump constructed according to this invention, and Fig. 2 is a cross-section taken on line m m in Fig. 1.

P is the pump-barrel, and 7c is the plunger working therein. A single suction-valve dis provided, and b and c are delivery-valves. All these valves are of any approved construction, and the delivery-valves communicate with the pump-barrel by separate pas- More than two delivery-passages may be provided if desired, each being furnished with a separate delivery-valve.

The plunger 7c is made hollow or provided with the passage p', which opens into the lower part of the pump-barrel, and p are passages connecting with said passage p and opening into the upper part of the pump-barrel. The lower openin g of the passage through the plunger is always in communication with the Suction and the upper opening with the delivery.

The plunger is revoluble within the barrel and is provided with the projecting arm a for turning it in either direction.

The pump can be made to deliverv into either of the delivery-passages by turning the plunger so as to place a passage p in communication with the selected delivery-passage. Any passage into which it is not desired to force the liquid is closed by the plunger, as shown in Fig. 2.

What I claim is- 1. The combination, with a pump-barrel provided with a suction-valve and separate delivery-passages, of a revoluble reciprocating plunger provided with a passage couimunicating with the suction-valve and with either of the delivery-passages according to the position to which the plunger has been turned, whereby the pump is adapted to deliver in different directions, substantially as set forth.

2. The combination, with a pump-barrel provided with a suction-valve and separate delivery-passages, of a revoluble reciprocating plunger provided with a passage constantly communicating with the suctionvalve, and passages constantly connecting the aforesaid passage with eitherof the deliverypassages according to the-position to which the plunger has been turned, whereby the pump is adapted to deliver in different directions, substantially as set forth.

3. The combination, with a pump-barrel provided with a suction-valve and separate delivery-passages, of a reciprocating plunger provided with a projecting arm, whereby it may be partially revolved within the vpumpbarrel, and having a passage constantly communicating with the suction-valve and adapted to be placed in communication with either of the said delivery-passages, according to the position to which the plunger has been turned by the said arm, substantially as set forth.

In testimony whereof I aflix mysignature in presence of witnesses.

CARL v. LDE.
